Does anyone try the Speed Chip stated that it will increase horsepower by adjusting the IAS sensors setting on ECU on their scion. You know those stuffs from ebay do not sound really reliable. If you have ever tried it, please share the result. Thanks!

 

There is not, nor will there ever be, a speed chip for the Scion tC.

 

why don't you try it and let us know

 

oh boy.
these chips do not work, for any car.
use the search feature before asking redundant questions.
thank you.

LOCKED!
